ASSIGNOR TO DUIBILIEB CONDENSER COB- PORATION, *A CORPORATION OFDELAWARE connnivsnn Application filed February 12,1924. Serial110.592.827.

This invention appertains to improvements in condensers, especiallycondensers for use in electrical circuits.

An object of my invention is to provide aconstruction wherein a greater,or smaller number of units, each comprising sheets or and of such acharacter that it can be built in sections, each of which can. beproperly attached to one or more other sections of the same sort, anddetached when required, with the result that when any part of theassembled device becomes defective or is damaged or impaired, theconsequences can be localized and remedied with the least possibleexpense, labor and difliculty.

Other advantages of my invention are set forth in the followingspecification, taken with the drawings, showing a preferred form of myinvention. The disclosure, however, is illustrative only, and I mayresort to variations in structure, not necessarily mentioned herein, butconstituting no departure from the principle of my invention, as definedby the broad and general meanings of the terms in which the appendedclaims are expressed.

On the drawings, Figure 1 is'a top planof a section of aconstructionaccording to my invention; and Figure 2 is a verticalsection thereof. The same numerals identify the same parts throughout.

I show at 1 in Figure 1 a plurality of units, each consisting of acomplete condenser, having sheets of conducting material C, separated bysheets of insulation or dielectric D;

4 indicated diagrammatically only on Figure 1.

The structure and design of these units are not materialto thisinvention, as the separate condensers may be made up in numerous ways. Iarrange the separate condensers in radial formation, with reference to acommon center or axis, like the spokes of a wheel, the separate sheetsC, and D being transverse to the radius extending lengthwise of eachunit. Half of the conductive sheets or elements 0 of each condenser willbe connected to a common pole or terminal and joined to a commonconductor at the center, while the remaining sheets C of each condenserwill be joined to another common conductor at the outer ends of thecondensers; so that the condensers thus arranged are in parallel. Themanner in which the two sets of conductive elements C of oppositepolarity are thus connected, will be apparent to those skilled in thisart and need not be particularly illustrated. The entire group ofcondensers is mounted in a housing consisting of a top plate 2,preferably of metal; and a similar bottom plate 3. These two plates aredished within their peripheries, the bottom plate being 111- verted; andbetween the two plates is a tubular part or hollow body 4, of .porcelainor other insulation, made fast to the top and bot- 1 tom plates at itsopposite upper and lower ends. Such a housing with a group of radialcondensers therein, as described, makes a complete section; and as manyof such sections can be employed in the aggregate as one wishes. InFigure 2, I show two such sections, one on top of the other; but agreater number can just as readily be employed, to build the apparatusup to any given height, for increased voltage or greater capacity.

At the center of each section is a head 5, supported by the top 2, as bya threaded stud made fast in the upper end of the head and passingthrough a central opening in the plate 2, where it is secured'b one ormore nuts 7 above the top plate. Ad acent its lower end this head has anumber of flat, plane lateral faces 8, against which the separate unitsor condensers are pressed. I surround the group of radially arrangedcondensers by a conductor ring 9, and at the adjacent end of eachcondenser is a thrust plate 10, engaged by a bolt 11. By turning thesebolts the condensers are forced into tight engagement with the faces 8of the'head 5, and each bolt can of course be made fast with one or morelock nuts 12 on the outside of the ring 9.

a" all This rin is supported on posts 13, secured Thus the portion 4;and the plates 2 and 3 are afined together, Betweenthe plates and thepart t are packing rings or gaskets 19, to seal the joints and enablethe housing to be made leak-proof, so that it can be filled with oil orThe circumferential flanges 20 of the plates 2 and 3 enable thedifferent sections to be joined together when more than crisis to beemployed as in Figure 2; these flanges having alined holes for headedbolts 21 to be engaged at their ends by nuts 22. Owing to the dishing ofthe plates 2 and 8, the sections will be in direct contact only theirflanges, and a chamber 23 will exist between each two sections, so as toprotect each section as much as possible from any heating effects in theadjacent sections;

The inner ends at the condensers l of each section are joined to the topplate 2 through the head 5 and the outer ends to the plate 3 through thering 9 and'posts 13, all the parts being of conductive material tor thepurpose. The condensers of each group are in parallel with each other,but the groups or the difi'erent sections are in series by reason of thejuncture of the top plate 2 of each section with the bottom plate OT thenext section above. To connect the entire device in circuit, the leadsare joined to uppermost plate 2 and lowermost plate 3.

llllach section can easily be dismounted, and the top plate 2 removed toobtain access to the condensers 1 therein. Any unit 1 can then readilybe taken out for repair, or a new one substituted. For such a purposethe operator need only remove the bolts 21 and 17 and the nut 7, andloosen the bolts 11. And if from any cause the construction should bebroken or damaged, or the porcelain a be cracked, the injury is confinedto one section only, and the loss of contents to the oil or WZLXtherein, the contents of the other sectionsbeing eil'ectually retained.U, i

The head 5 the ring 9, between which the condensers are clamped, serveboth as supporting means and as terminals tor the condensers of eachsection to connect the condensers to the top 2 and. bottom 3 which areclosures for the opposite upper and lower ends of each housing orsection, as well as terminals; so that when two or more sections areassembled andsecured with'their flanges 20 in contact, the condensers ofone are at once placed in circuit with the condensers of the other orothers.
